    摘要： Machine-readable coded data disposed on or in a substrate. The coded data includes a plurality of layouts located in a region, each layout having n identical sub-layouts rotated 1/n revolutions apart about a center of rotation. Each layout encoding a first codeword formed from a sequence of n first symbols, with each sub-layout defining the position of a respective one of the first symbols such that the first codeword is indicative of the orientation of the layout. Each layout also partially encodes a third codeword at least partially indicative of an identity of the region such that the region identity may be determined from two or more of the layouts.

    摘要： A dithering unit for a multi-segment printhead having a plurality of printhead segments that are positioned in a printhead to span a print area so that portions of consecutive printhead segments overlap in common print areas, with each printhead segment defining a lead-in area in one common print area and a lead-out area in a consecutive common print area, the dithering unit being configured to communicate with an interface to receive image data from the interface and a memory device to receive data relating to the characteristics of the multi-segment printhead, the dithering unit being configured to generate a set of dither matrices for each printhead segment so that each set has at least a lead-in dither matrix associated with the lead-in area and a lead-out dither matrix associated with the lead-out area, to generate lead-in/lead-out dither matrices for each common print area based on characteristics of the printhead segments of each common print area, to generate a variable probability value that is dependent on a scalar value that corresponds to a position along a line spanning each common print area and to interpolate the lead-in/lead-out dither matrices with the variable probability value to generate interpolated lead-in/lead-out dither matrices.

    摘要： A printer with a multi-segment printhead has multiple engine/controllers (10) configured to be coupled with other engine/controllers to drive the printhead (33). The controllers each have an interface (27) at which to receive compressed page data. Image decoders (28, 88) decode compressed image planes image decoders to perform an expansion, in pipeline fashion, for the received compressed page data. A half-toner/compositer (29) composites respective strips of the decoded image planes and sends output to a printhead interface (32). A printhead interface (32) interfaces with the printhead. A synchronization signal generator (89,90) may output a synchronization signal that is used to synchronize print engine/controllers. One printhead interface (32) preferably acts as master generating the synchronization signal to synchronize all the print engine/controllers to drive the printhead at any one or more of higher speed, higher input resolution, higher outlet resolution or wider format. The half-toner/compositor (29) scales input image planes under control of a margin unit (57) set the print engine/controller to establish print data for a strip only of the image, the image being built from the respective strips from the multiple print engine/controllers.
